Little Snitch: Robust firewall app for macOS. Control outbound connections, block unwanted apps & prevent unauthorized data transmission. Real-time alerts & rule-based blocking.
Little Snitch is a powerful Mac application designed to monitor and control internet connections made by applications on your system. This tool allows users to selectively allow or deny network access for specific apps, providing real-time visibility into internet activity. Little Snitch automatically manages new connections in “Silent Mode” while tracking all outgoing connections, including data volume, server location, and used ports/protocols. Users can analyze communication patterns through an interactive traffic chart spanning up to a year, identifying unusual or suspicious data transmissions. With features like search functionality, a Control Center for managing network activity, and support for blocklists and IP-based blocking (updated daily), Little Snitch enhances both security and control over your Mac’s internet connections. Furthermore, it encrypts DNS requests using trusted services like Quad9, further improving privacy and security.
